A Roblox card in NZD does not give 4,000 Robux exactly; the closest common value is usually the NZ$50 card, which is listed at about 4,500 Robux in one NZ pricing table. That means 4,000 Robux is roughly around NZ$45–50 , depending on the pack and any Roblox pricing differences.

Quick Scoop

Here’s the simple breakdown from the available pricing examples:

Robux amount Approx. NZD
400 Robux NZ$6.49
800 Robux NZ$12.49
4,500 Robux NZ$50
That makes **4,000 Robux** land just under the 4,500-Robux NZ$50 card tier, so **NZ$50 is the nearest practical card value**.

Bottom Line

If you want exactly 4,000 Robux , Roblox gift cards usually won’t match that number perfectly. In practice, you’d likely need to buy the NZ$50 option and get a little extra Robux rather than an exact 4,000.
